Title: Vibration-damping explosion control valve
Inventor: MALCOLM EDDIE R
IPC: B04C11/00
Filed: 1987-05-22
Abstract: A burst panel assembly (10) for normally covering a vent opening of structure which defines an area to be protected from the buildup of dangerously high internal pressures has two frangible panels (l2, l6) disposed in spaced, face-to-face relationship along with a core of expanded polyurethane foam (48) which functions to dampen vibrations received from the structure and transmitted to the frangible panels (l2, l6). The foam (48) is introduced in an initially flowable condition into the space (20) between the panels (l2, l6) and thereafter expands while curing to a solidified configuration for continuously exerting pressure on both of the panels (l2, l6), to thereby substantially reduce the fatigue stress that would otherwise occur along lines of weakness of burst patterns (22) that are formed in both of the panels. In a preferred method of construction of the burst panel assembly, pressurized air is initially introduced into the space between the panels (l2, l6) to shift one of the panels outwardly to a pre-bulged configuration, and subsequently a negative pressure is applied to the outside face of the opposite panel to shift the same in an outward direction while filling the space (20) with the initially flowable foam material (48), so that the foam expands to a configuration larger than would be otherwise possible and is subsequently "pre-stressed" against the same panel when the negative pressure is relieved. The foam material (48) when cured strengthens the assembly by providing support to the central portions of the frangible panels (l2, l6), and also the foam (48) is compressible and somewhat resilient so that vibrations transmitted to the frangible panels are effectively dampened. The burst panel assembly is particularly useful for protecting relatively low pressure equipment such as baghouses, dust collectors and dryers.

Title: Driving system for liquid crystal display unit
Inventor: NAITOU OKITO
IPC: G02F1/133
Filed: 1977-10-20
Abstract: PURPOSE:To reduce the picture blur as well as to lower the cost and facilitate an easy IC formation by carrying out the scanning of the full picture element with m- field ( m 2 ) of the video to lower the scanning frequency of the liquid crystal matrix (down to 1/2 or less). CONSTITUTION:The (xXy)-units of the full picture element are scanned with m-field (m>=2); N/m-times of scanning (N: number of pieces of scanning line) are carried out; and the picture element of x/N/m-line and y/m-line is driven by one-time scanning to drive all picture elements through N-times of scanning. In the case of m=2, N=41, x=81 and y=108 respectively, 21 pieces in all of X1-X21 are scanned at the first field for scanning electrodes X1-X41 (scanning time 12H a piece), and 20 pieces in all of X22-X41 are scanned in the second field. Thus, 4 lines of picture elements are driven within 12H of one scan. Accordingly, the luminance modulation signals are applied to signal electrodes Y1-Y108 in accordance with the digital data with 3H intervals of the TV video signal. In this case, the sampling frequency is within 55 or 54 times at the A/D conversion time, reducing down to 1/2 of conventional times (108).
